But none has been tighter than the leather catsuit she wears as a sexy spy in upcoming movie Marvel Avengers Assemble.
The 27-year-old revealed the outfit was getting her literally hot under the collar as she spilled behind-the-scenes secrets of the superhero sensation, due for release on April 26.
Speaking from the set in New Mexico, she said: “Everybody on the film has their own uncomfortable costume situation. It’s like 800° in mine. And it’s a one-piece and I have nothing underneath it.”
According to Scarlett, costumes in Marvel Avengers Assemble are the most daring of her career to date.
She described the cast’s dressing process as “very surreal”, adding: “It was kind of an out-of-body experience. Like a dress-up, but to the extreme.
“Everybody looks incredibly uncomfortable until the cameras are rolling.
“Then we all look badass. And when the Avengers assemble, it feels like being a little kid.
“Then, cut! And we’re all like, ‘Arrgh, God, get this thing off me.’ As soon as everything is cut, everything comes off.
